Application filed May 11, 1918. Serial No. 98,781.

To allwliomzt may concern:

Be'it known that I, ERASTUS E. WINKLEY,

a citizen of the United States, residing at L nn, in the county of Essexand State of assachusetts, have invented certain new and usefulImprovements in Shank-Edge Trimmers; and I do hereby declare thefollowin to be a full, clear, and exact dc.- scri tlon of the invention,such as will ena 1e others skilled in the art to' which it ap ertains tomake and use the same.

his invention relates to a machine for operating upon shoes, and it hasspecial reference to machines for finishing sole edges, and particularlyfor trimming, or partially trimming, the edges of they shank of theoutby a special machine for that purpose. This heel-jointing isnecessary both because theordinary rotary trimming-cutter cannot work upinto the angle between the sole and the breast of the heel, and becausethe shank must be trimmed at its rear e'xtremity, in order to produce aneat finish, with reference to the finished surfaces of the heel and notwith reference to the hottom of the crease.

The present inventor has devised a method of making shoes, set forth andclaimed in a co-pending divisional application, Serial No. 371,917,filed April 7 1920, in accordance with which the shank-edges are trimmedbefore the application of the heel, and in which the heel is alsofinished before its application, and one object of the present inventionis to produce a machine adapted particularly for performing apreliminary shank-edge trimmlng operation in carrying out the methodabove referred to.

For this purpose the machine is provided with novel means for gaging thedepth of the cuts produced in the trimming operation so that this depth,instead of belng determined either by the skill of the operator orcharacteristics thereof.

by reference to the crease of the shoe, shall be so determmed that thetrimmed shankedges shall exactly co incide,-at the rear extrem1t ,-w1ththe finished surfaces of the heel w en the latter is subsequentlyapplied. Smce the location of the heel is determined, 1n the methodabovereferred to, with reference to the orlginal outline of the sole,andpreferably by a tongue or narrow extenslon at the rear extremity of theshank, the machine of the present invention is so con structed as to therear extremlty of the shank, in accordance with the original outline ofthe sole,

and preferably by coo eration of its gag-.

ing mechanism with t ferred to.

In another and broader aspect, ,an object of the present invention is toprovide a shoe machine which shall perform its intended operation orfunction upon each shoe. pree tongue above resented thereto inaccordance with the particular characteristics of the individual shoebeing operated upon. To this end, a feature of the invention resides inthe provision of operating means which is prescribed in its action bymovable guiding means that is provided with means constructed andarranged to enga e each shoe operated upon for adjusting t e position ofthe iding,

means in accordance with the in ividual Other objects of the invention,and the various features of construction bywhich these objects areattained, will be set forth hereinafter, in connection with thedescription of the illustratedembodiment of the invention.

In the accompanying drawings Figure 1 is a side-elevation of a machineembodying the present invention; Fig. 2 is a planview of a portion of ashoe, showing the character 0 the Work performed by the machine; Fig. 3is a plan-view of the machine, on a larger scale than Fig. 1; Fig. 4 isa front-elevation of the upper portion of the machine, with a part ofthe crossbar broken away; Fig. 5 is a frontselevation of the lowerportion of the machine, on a smaller scale than Fig. 4; Fig. 6 is averticalsection on the line 66 in Fig. 3, but on a larger scale than thelatter figure; Fig. 7 is a section on the line 7-7 in Fig. 1, lookingupwardly and on a-larger scale than ge. the trimming-cuts, at

the latter figure; Fig. 8 is a horizontal section on the line 8-8 inFig. 5; and Fig. 9 is a vertical section on the line 99 in Fig. l.

The construction and operation of the machine may be best understood inview of the character of the "work which it performs. Fig. 2 shows aportion of a lasted shoe, of which the outer sole 11 has been stitchedin place and the heel 13 has also been aflixed. In this shoe, ashereinbefore described, the sole is provided with a rearward extensionor tongue 12 from the rear extremity of the shank-portion of the sole,this tongue being narrower than the shank-portion. The heel is finishedbefore its application, and it is provided with a recess which receivesthe tongue 12, and whereby the heel is located accurately with respectto the shank of the sole. The edges of the shank-portion have beentrimmed previous to the application of the heel, as shown by shading inFig. 2, the trimming operation involving the removal of the surplusmaterial which is shown by the dotted lines 14 constituting a part ofthe original outline of the sole.

The principal function of the present machine is to perform thepreliminary trimming operation in such a manner that the rearextremities. of the trimming-cuts shall leave the shank-portion of theshoe, at its rear extremity, with an outline having an exact relation tothe width and location of the tongue 12, so that when the previouslyfinished heel 13 is placed on the sole the finished lateral surfaces ofthe heel shall be exactly contiguous with the trimmed edges of theshank.

A subsidiary function of the machine is to facilitate the smoothblending of the short trimming-cuts performed by the machine. with thetrimming-cuts which may be subsequently performed in the usual manner,in trimming the rest of the shank. This latter trimming operation isguided with reference, not to the original outline of the sole, butrather to the position of other parts of .the shoe, particularly thebottom of the crease between the welt and the upper.

The operative instrumentalities of the present machine comprise, asshown particularly in' Fig. 7, two rotary trimming-cutters or tools 15,which operate progressively along the sole-edge toward the rearextremities of the shank. The position of the shoe during the trimmingoperation is accurately and automatically determined with reference tofour points of the shoe. Two of these points are the angles between thetongue 12 and the rear extremity of the shank-portion. For this purposethe machine is provided with two gages 16, which may be described astongue-gages. The other two points of location are at the bottom of thecrease, slightly in advance of the points at which the trimming-cuts arecommenced, and these gagingpoint are located by means of two creasegages17. having acute ends adapted to enter the creases to the bottomsthereof. In Fig. 7 the sole 11 only of the shoe is shown. for thepurpose of illustration, the other parts of the shoe, which are abovethe sectioirplanc, being omitted, and the bottoms of the crease areindicated by broken lines 18.

\Vhen the shoe has been located in the machine by the four gages justdescribed, the paths of operation of the trimming-cutters are determinedwith reference to the positions of the gages. For this purpose thecutters are rotatably mounted upon laterally-movable slides 19 (Fig. 7),which are provided with guide-rollers 21. Each of these rollers movesalong the outer cam-like surface of a cutter-guide or templet in theform of a bar 22. The rear end of each guide is attached, by a pivot 23,to a bracket 24 extending forwardly from a slide 25 upon which one ofthe tongue-gages 16 is also rigidly mounted. The slides 25 movelaterally in a gu deway 20 on the frame of the machine. Since the pivots23 are laterally in line with the rear extremity of the shank when thetongue-gages are in engagement with the angle between the tongue and theshank, as shown in Fig. 7, the depth of the cuts produced by thetrimming-tools is exactly determined, at the rear extremity of theshank, in accordance with the width of the tongue. Since, also, the solewith the tongue is produced by a dieing-out operation which positivelydetermines the relative widths and positions of the tongue and theshank, it follows that the trimming-cuts have, at the rear extremity ofthe shank, a definite relation to the original outline of the shank atthis point.

It will be observed, also, that the cutter guides or templets 22 are ofsuch length as to extend beyond the heel end of the shankedge, of theshort outsole illustrated in Fig. 7. and that their curvature is suchthat the rolls 21, in traveling over them, carry the cutters 15 in apath in extension of the curvature of the shank-edge as they leaveengagement with the sole. This provides for an exact width of sole atthe heel end of the shank equal to the width of the breast of the heel,and a sharp corner on the short outsole to abut the heel breast.

The forward ends of the cutter-guides 22 are connected, by pivots 26,with two slides 27, and the crease-gages 17 are also mounted on theseslides. For this purpose the creasegages are provided with shanks 54which are fastened, by set-screws, in sleeves 55 integral with theslides. The slides move laterally in slide-guides 56 on the frame of themachine.

Since the position of the forward ends of" the cutter-guides isdetermined by reference to the creases of the shoe, it follows that thetrimming-cuts, at their forward extremities, are regulated as to depthand pos1t1on by reference rather to the position of the crease or edgeofthe last within the shoe, than to the original outline of theshoe-sole, and accordingly the trimming-cuts produced by the presentmachine may be smoothly blended, at their forward extremities, withtrimming-cuts produced in the usual manner and gaged by the crease ofthe shoe.

Prior tothe introduction of the shoe between the gages it is necessaryto draw these gages apart, and for this purpose mechanism 1s employedwhich is operated by a treadle. To each of the slides 25 a link 28 is attached, by a pivot-screw 29, and the outer ends of the links are pivotedto arms 31 constituting parts of two bellorank levers which swing aboutpivot-rods 32 fixed vertically on the frame of the machine. The secondarms 33 of the respective bell-crank levers are connected, by shortlinks 34 (Figs. 6 and 9), with the upper and lower ends of a head 35which slides horizontally on a rod 36. This rod is fixed in brackets 37on the frame of the machine. A tensionspring 38 (Figs. 7 and 9),connected at its ends wi+h the two leverarms 31, tends to draw themtogether so as to move the tongue-gages 16 toward each other,.and thearrangement of the levers and the head 35 is such as to cause themovements of the levers and of the tongue-gages to be always e ual andin opposite dlrections, so that w en the parts are released from theoperation of the treadle 52 (Fig. 1) the spring 38 causes the gages tocentralize the tongue as well as to press against the sides of it. Atthe same time the operator pushes the shoe rearwardly, so as to causethe rear extremity of the shank to engage the tongue-gages.

The head 35 is connected, by a pivot-pin 39, with a link 41 (Fig. 7)which is pivoted to the upper end of a lever 42. This lever is mountedto swing freely on a rod 43 fixed in the frame of the machine. The lever42 is provided with a lug 44, in position t be engaged by anadjustablescrew 45 (Fig. 1) carried bya yoke-shaped lever 46 which alsoturns upon the rod 43. The lever 46 has an arm 47 which is connected, bya rod 48, with a lever-arm 49. The arm 49 is integral with a sleeve 50(Fig. 5), whichturns on a rod 51 fixed at the bottom of the frame of themachine. A treadlelever 52 is also integral with the sleeve 50. A spring53, attached to the treadle-lever, holds it normally in raised position.When the treadle is depressed the lever 46 is swung in a direction tocause the screw 45 to swing the lever 42 forwardly, thus slid ing thehead 35 forwardly on the rod 36 and causing the tongue-gages to be movedapart. When the parts are n their normal .anism very simi position thescrew 45 is out of engagement with thelug 44, so that the tongue-gagesare free to assume their proper operative positions under the influenceof the spring 38. i

The crease-gages are controlled by mechar to,

(Fig. 7) are'connected, by pivot-pins 58, with arms 57 constitutingparts of two bell-crank levers which turn on the rods 32. The other arms59 of the levers are connected, by links 61, with a head 62 (Fig. 9)which slides on a rod 63 mounted in the brackets 37; This head isconnected, by a link 64 (Fig. 7), with alever 65 arranged alongside thelever 42. The lever 65 cooperateswith a second screw 66, carried by thelever 46, so that when the treadle 52 is '70 and in part common w1th,that just described. The slides 27.

depressed the. crease-gages are-moved apart in the same manner as thetongue-gages. The crease-gages are drawn toward each other by theoperation of a tension-spring 67 (Figs. 7 and 9) which connects theleverarms 57.

The trimming-cutters, in addition to rotating, are moved inwardly andoutwardly to engagethem with and disengage them from the work and toregulate the depth of the cuts produced, and they are also moved in afore-and-aft direction to cause them to act progressively on the shankand then to return to their original positions. To cause the rotation ofthe cutters each cutter is mounted on a vertical shaft 68 (Figs. 4 and8), which turns in upper and lower bearing-sleeve 70 and 80. Thesesleeves are connected by an integral yoke, as shown in dotted lines inFig. 4, and each sleeve 70 is integral with the corresponding slide 19.

Between the bearing-sleeves each shaft carries a pulley which isconnected, by a belt 78, with a drive-pulley 76. 1

It is necessary to maintain, duringv the fore-and-aft movements of thecutters, a constant distance between thecutter-shafts and thedrive-pulley 76. Accordingly these parts are connected together byasingle fore-and-aft slide. The frameof the machine is provided, at thetop, with two longitudinal slide-guides 71 (Figs. 4 and 6), and theslides 19 move in a transverse guideway 69 which is connected withrearwardly extending slide-bars 72 which move in the slide-guides 71.The bars 72- are connected, at their rear ends, by a yoke 73 and across-bar 74, as shown particularly in Figs. 1 and 9. Cheeks 75, whichrise from the sides of the slide, provide. bearings for the shaft of thedrive-pulley 76, and also for the shaft of an idler-pulley 77 which islocated in front of the nulley 76 so as to guide the quarter-turn belts78. The drive-pulley is connected, by a vertical belt 79 (Fig. .1) witha pulley 81 mounted on the power-shaft 82 of the machine. This shaft isdriven constantly by connection with any suitable source of power.

The movements of the trimming-cutters are performed automaticallythrough a complete cycle, the commencement ot'the movements beingdetermined by the operator. For this purpose, the slides which controlthe -movements of the cutters are actuated by a cam mechanism driventhrough a Horton or one-revolution clutch. The power-shaft 82 isconnected, by mitergears 84 (Fig. with a vertical wormshaft 86 which isjournaled in the frame of the machine. The worm-shaft carries a wormwhich meshes with a worm-wheel 88 (Fig. 8) rotatable about a cam-shaft90 which is journaled in the frame.

The \\'oi'm-wlieel is connected with one member of. a Horton clutch 92,of which the other member is fixed to the shaft. The construction ofthis clutch is not particularly illustrated, as devices of the kind arewell known, but it will be understood that the operation of the clutchis controlled, in the usual manner, by means of a stop-member 94 whichis provided with a shoulder, as shown in dotted lines in Fig. 1,arranged to coiiperate with a lug on one end of a detentlever 96, whichis pivoted on the frame of the machine. A spring 98 connected to thelever 96 tends to throw it upwardly so as to engage the shoulder andarrest the movement of the clutch at the completion of each rotation. Topermit the clutch to be thrown into operation the detent-lever isconnected, by a rod 100, with a treadle-lever 102, which is normallyheld in its upper position by connection with the same spring 98 bywhich the detent-lever is controlled. Each time the treadle 102 isdepressed and released the cam-shaft 90 performs one complete rotationand then comes to rest.

The transverse movements of the slides 19, by which the trimming-cuttersare brought into and out of engagement with the work. are controlled bya cam 104 (Figs. 5 and 8) on the cam-shaft 90. This cam engages a roller106 on onearm 108 of a bell-crank lever which turns loosely on a rod 110fixed on the frame of the machine. The other arm 112 of the bell-cranklever is connected, by a rod 114, with one arm 116 (Fig. 9) of a secondhell-crank lever, which turns loosely on a rod 118 which is supported inbrackets 119 on the frame of the machine. A second arm 120, integralwith the arm 116. is connected, by a link 122, with an arm 124 dependingfrom a sleeve 125. The sleeve turns loosely on a rod 126 which issupported in uprights 127. From the middle of the sleeve 125 an arm 128projects forwardly, and is provided with a wide end which is adapted toengage simultaneously the ends of two arms 130 (Figs. 3 and 4)projecting from sleeves 132. These sleeves are fixed on rods 134 whichare journaled, in parallel positions. in bearings 1.36 on the frame ofthe machine. From each sleeve 132 two arms 138 depend, and support ahorizontal rod 140. Each of the rods 140 pass through a horizontalopening in the yoke which connects the upper and lower bearings and 80in which one of the cutter-shafts G8 is supported, as shown particularlyin Fig. 4. This arrangement is such that while the rods 140 do notinterfere with fore-and-aft movements of the yokes. they cause theyokes, and thus the slides 19 and the trimming-cutters, to movetransversely when the arms 138 are rocked. The inward movement of thearms 138 is caused by springs 142, which are coiled around the rods 134,as shown in Fig. 9. and are connected. at their opposite ends, with thebearings 136 and collars on the ends of the rods. The engagement of thecutters with the work is accordingly produced by the resilient action ofthe springs. The opposite or disengaging movement of the cutters isproduced positively, by the action of the cam 104 and the interveningmechanism above described.

The fore-and-aft movements of the cutters. by which they are caused totraverse the sole-edge and also to return to their original positions,is produced by a cam 144 (Figs. 5 and 8) on the cam-shaft 90. This camengages a roller 146 carried by one arm 148 of a bell-crank leverpivoted on the rod 110. and the other arm 150 of the lever is connected,by a rod- 152, with a bell-crank lever 154 (Fig. 7) which is mounted onthe rod 118. The other arm 156 (Fig. 9)- of the latter bell-crank leveris connected, by a link 158, with a bearing-lug on the cross-bar 74which forms a part of the fore-and-aft slide by which the slideuide 69is supported. This slide is, therei ore, moved positively by the actionof the cam 144, in proper timed cotiperation with the other parts of themechanism.

To insure an exact registry of the trimming-cutters with the edges ofthe shank each cutter is provided with a smooth flange 160 (Figs. 7 and9), which is adapted to enter the crease of the shoe and bear againstthe grain surface of the welt. This flange is not designed, however, tolimit the movement of the trimming-cutter by engagement with the bottomof the crease, since this function is performed, in the present machine,by the guiding-mechanisms heretofore described.

A chute 162 (Figs. 1 and 9) is provided beneath the trimming-cutters toreceive the material removed. The chute may be connected, in the usualmanner, with an exhauster to carry away the dust.

The operation of the machine, asa whole, is as follows: In the normalposition of the parts the trimming-cutters are in their fore-v mostposition and are widely separated from each other, and all parts of themachine are at rest, except the power-shaft 82 and the belt-connectionsby which the trimmingcutters are constantly rotated. The operator holdsthe lasted shoe, on which a short outsole has been laid, in invertedposition and introduces it between the cutters so as to bring the tongue12 of such an outsole into a position between the tongue-gages 16;

While so introducing the work the operator holds the treadle 52 indepressed position, so that the tongue-gages and the cross-gages areheld widely apart. The operator then releases the treadle 52, allowingthe gages to seat themselves against the work, and at the same timepresses the shoe rearwardly to cause the tongue-gages to be engaged bythe shoulders at the extremities of the shank of the sole, formed by thetongue 12. The operator then depresses and releases the treadle 102.This causes the clutch to im-- part one-rotation to the cam-shaft 90,and by the action of the cams, as above described, the trimming-cuttersare caused, first, to approach and cut into the work to the depthdetermined by the guides or templets 22, then to move to and past therear extremities of the shank, so as to trim these extremities to acontour determined by the gages, then to move away from each other andout of engagement with the work, and finally, to

return to their. original position and come to rest, the cycle ofoperations of the machine being thus completed. The operator then againdepresses the treadle 52, removes thetrimmed shoe, and substitutesanother.

The invention has been illustrated and described as embodied in amachine arranged to trim only therear portions of the shankedges, asthis is the function for which the machine is particularly designed, butit Will be apparent, that the invention is not limited to embodiment ina machine arranged to opcrate in this restrictedmanner, I
